Definitions

  • the invention relates to extruded aluminum alloy products Al-Mg-Si (6000 series according to the nomenclature of the Aluminum Association) with improved corrosion resistance, in particular drawn tubes intended in particular for pipes or heat exchangers. thermal for automotive construction.
  • HFCs HydroFluoroCarbures
  • An air conditioner using CO2 as a refrigerant gas is based on gas compression and expansion.
  • a compressor compresses the CO2 at high pressure and it then goes into a gas cooler (traditionally called a condenser, but in which condensation does not occur when the refrigerant is CO2), then in an internal heat exchanger (which allows heat exchange with the low pressure zone).
  • the CO2 which is still gaseous, then passes into a regulator from which a liquid flows out which allows the cooling of the passenger compartment by passing through an evaporator.
  • the low pressure gas is then accumulated before circulating in the internal heat exchanger and back into the compressor for a new cycle.
  • the spun aluminum products can be used for the manufacture of heat exchangers (gas cooler, evaporator) and / or for the realization of the pipes allowing the refrigerant to circulate between the various elements of the cooling circuit.
  • CO2 as a refrigerant is made difficult by the pressure at which it must be used. Indeed, the critical temperature of CO2 is lower than that of HFC-134a and its critical pressure is higher which forces the air conditioning system to operate at higher pressures and temperatures than those currently used, whether in the high pressure part or the low pressure part of the circuit.
  • the materials used in the air conditioning circuit must therefore be stronger than current materials while maintaining at least equivalent performance in terms of manufacturing, shaping, assembly and corrosion resistance.
  • the CO2 thus needs to be compressed at high pressures of the order of 100 to 200 bar. Therefore, to allow the use of CO2 as a refrigerant, the pipes must withstand an operating pressure of 200 bar for high temperatures of 130-170 ° C which is high compared to current conditions, the order of 5 bars at 60 ° C.

For economic reasons of recycling, the iron content must be at least 0.1% by weight and preferably at least 0.15% by weight.
